MACHINE FOR WASHING PLATES OR OTHER DISHES.

SPECIFICATION forming part of Letters Patent N o. 681,113, dated August20, 1901i.

Application led June 12, 1899. Renewed July 22, 1901. Serial No. 69,314.(No model.)

To @ZZ wiz/m it may concern,.-

Be it known that I, JOHANNES DNNER, manufacturer, a citizen ofSwitzerland, residing at Berne, Switzerland, have invented certain newand useful Improvements in Machines for Washing Plates or other Dishes;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

The objects of this invention are to construct a machine for washingplates and other dishes which will be very efficient, simple in itsoperation, and assure a thorough cleaning of the plates, the machinebeing especially designed for hotels, eating-houses, and the like.

The invention consists in an improved machine in which the plates aremoved in hot water between suitable brushes and in the arrangement andcombination of the parts thereof, as will be hereinafter more fullydescribed.

y ward in the tank a.

In the accompanyingdrawings like letters of reference indicate similarparts in all the views in which they occur.

In the said drawings, Figure l is a section Online .fr ai of Fig. 3,showing the arrangement of the brushes. Fig. 2 is a section on line y yof Fig. 3 with the brushes removed to more clearly show the brackets,and Fig. 3 is a plan view.

The machine consists of a tank a, which can be filledV with hot Waterand in which is supported a frame b, having brackets c to receive theplates. This frame is carried by a vertical shaft d, with which it isallowed to turn freely. The mechanism which serves to rotate the fralneb is secured to a support e, and from this support brushes f extenddown- These brushes are so arranged that the plates held by the bracketsc can be moved between said brushes in such a manner that the plates aretouched and rubbed on both sides by the former.

By means of the angular gears g g', the shaft h, and the crank iltheframe ZJ can be quickly rotated, and thus the plates held in thebrackets c are cleaned not only by the brushes f, but the hot water,too, assists Jthe cleaning, as the plates are moved at considerablespeed through same.

The brackets c are so arranged upon the frame b that the plates take aposition such as to afford the least possible resistance to the waterand brushes when turning with the frame b.

The greasy substances which during the washing operation accumulate ontop of the water constantly flow off at le and escape down the hollowstopper Z, and the tank a is emptied through openings m and the one'closed by the hollow stopper.

Having thus described my invention, what I claim is- 1. In a device ofthe character described, the combination of a receptacle for hot water,a rotary frame having a plurality of brackets adapted to support thedishes in a vertical position, arranged in series of two each andsubstantially radial to its axis, and a single diametric line of brushesthrough which the dishes have to pass in revolution, whereby the latterare cleansed on both sides, substantially as described.

2. In a device of the character described, the combination of areceptacle for hot water, the support e at top thereof, a vertical shaftd in said support, a rotary frame b rigid on said shaft and having aplurality of radiallydisposed brackets c arranged in series of two each,adapted t0 support the dishes in a vertical position, a series ofstationary brushes, arranged in a single diametrical line with respectto the receptacle through which the dishes have to pass in revolution,the shaft h transversely mounted on support e, said shaft served at oneend with a crank i, and bevelgearing adapted to transmit motion fromsaid shaft h to the vertical shaft d as and for the purpose set forth.

3. In a device of the character described, the combination of areceptacle for hot water, having a divided portion with outlets, asdescribed, a rotary frame having a plurality of brackets adapted tosupport the dishes in a vertical position, arranged in series of twoeach and substantially radial to the axis of the frame, and a cross-bare on top of the receptacle and a series of stationary brushes fdependingtherefrom through which the dishes have to pass in revolution,wherebythe latter are thoroughly cleansed on both sides, substantially asdescribed.

In testimony whereof I affix my signature in presence of two witnesses.

JOHANNES DUNNER.
